Variant setup for Kitbash parts

Another workflow idea (since there is support for exporting USD files) is to allow setting up simple variant switching for parts in the editor.

Like for example, I add a wheel first and then assign two other wheel variants to it so that I can encapsulate design choices and save them as USD!

This is an awesome idea @satishgoda.  Thanks for sharing!

Follow up question... would you expect parts to come into Falcon already having variants?  For instance with your wheel example, would you want to be able to drag a wheel in from the browser and then be able to quickly switch to any other available wheels directly in the app?

I think both are useful.

1. If a part ships with variants, the UI will mark it accordingly and users can add it and then switch as desired.
2. If a part does not ship with variants, the user will build it on the fly during the session.
